VALVE FOR BUCKET-'BOTTOMS.

SPECIFICATION forming part 0f Letters Patent No. 724,605, dated April 7,1903. Application filed October 7, 1901. Serial No. 77.899. (No model.)

To all whom it may concern:

Be it known that we, WILLIAM F. NORMAN and JOHN H. BERcHAUsER, citizensof the United States, residing .at Nevada, in the county of Vernon andState of Missouri, have invented a new and useful Valve for Bucket-Bottonis, of which the following is a specification.

This invention relates bucket bottoms.

The object of the invention is to present a valve that shall be positiveand certain in op: eration to open and close the opening in the bottomof the bucket and one which owing to its simplicity of construction andease of action will not be liable in use to become disarranged or brokenand which when once associated with the bucket-bottom may be relied onfor almost indefinite use without requiring any attention.

A further object is to provide a valve all parts of which aredisconnected from the bucket-bottom, thereby obviating the necestovalves for wellsity of the employment of screws or other fastening meansfor holding the valve assembled with the bottom which are liable to rustaway or become disconnected from the bottom, and thereby render thevalve inoperative.

A further object is to present a valve the packing of which shall be soassociated with its support as to be caused to retain its initial shape,thus to efiect the requisite closing of the opening in the bucket-bottomeven after the packing has become saturated with water or the like,andthus extremely soft and pliable.

With these and other objects in view, as will appear as the nature ofthe invention is better understood, the same consists in the novelconstruction and combination of parts of avalve for well-bucket bottoms,as will be hereinafter fully described and claimed.

In the accompanying drawings, forming a part of this specification, andin which like numerals of reference indicate corresponding parts, thereis illustrated one form of embodiment of the invention capable ofcarrying the same into practical operation, it being understood that theelements therein exhibited may be varied or changed as to shape,proportion, and exact manner of assemblage without departing from thescope of the invention, and in these drawings Figure 1 is a view insectional elevation of.

a valve characterizing this invention, showing the same in operativerelation with a wellbucket bottom. Fig. 2 is a detached detail v ew inperspective of the valve.

Referring to the d'rawings,,1 designates a bucket-bottom such as isemployed in connection with that class of buckets used in elevatingwater from bored or other .Wells, the center of which is provided withan opening 2 for the admission and escape of water.

The valve, (designated generally 3,) which constitutes the gist of thepresent'invention, comprises a valve proper, composed of a cap 4: and apacking 5, a yoke 6, constituting a stem, and a stop or cross-bar 7,these parts being all rigidly assembled, as by rivets S. The packing 5is composed of a suitable absorbent material, preferably of leather, andis concavo-convex in crosssection, the under side of its rim only beingdesigned to bear upon the bottom 1, thereby to effect perfect closure ofthe opening 2. In order to retain the packing in the shape initiallygiven to it, it is reinforced on its upper side by t he concavo-convexcap 4,which latter is of sufiiciently less diameter than the packing topermit the latter to have requisite yield to effect perfect closing ofthe opening 2 when the valve is seated. In order that the life of thevalve may be insured, all of the metallic parts thereof are ofgalvanized iron, with the exception of rivets 8, which may be of copper.The yoke 6, to which the valve proper is secured, is approximatelyV-shaped in side elevation, the upper portions of the arms thereof beingturned at an angle to their length, as at 9, to present attaching meansfor the valve proper, the arms being spaced at such distance apart as topermit the yoke freely to move in the opening 2 without any danger ofbinding. To the bottom bend 10 of the yoke is secured the stop orcross-bar 7, which latter is to be of a width to span the opening 2 atall times, thereby to insure positive operation of the valve withoutdanger of disassociation from the bucket-bottom. By securing the stop tothe yoke, and thus presentin gin a single structure all of the operativeparts of the valve, the employment of screws or other holding means forholding the stop associated with the bucket-bottom, as is usuallyemployed, is rendered unnecessary. This latter arrangement will beappreciated by users, as in the event of the cross-bar becoming detachedfrom the bucket-bottom, especially when the bucket is submerged in thewell, great inconvenience might ensue, as a new cross-bar might not beobtainable. Under the structure shown in this device this defect isobviated in a thoroughly practical and feasible manner.

In addition to the function already described the cross-bar operates asa counterweight to efiect seating of the valve in a positive manner, itbeing seen that by having it located by the crest of the yoke it willoperate to efiect quick seating of the valve as soon as upward movementof the bucket begins.

Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent, is-

1. A valve for well-bucket bottoms comprising a yoke carrying at one enda transversely-disposed stop constituting a counterweight, and at theother end a concavo-convex exteriorly-reinforced packing.

2. A valve for well-bucket bottoms comprising a yoke carrying at one enda transversely-disposed stop constituting a counterweight, and at theother end a concavo-convex packing and a similarly-shapedexteriorly-arranged reinforcing-cap of less diameter than the packing.

3. A valve for well-bucket bottoms, comprising a yoke carrying at itslower portion a rigid stop or cross-bar constituting valveseating means,and at its upper portion a con cave-convex packing and a reinforcing-captherefor, all of the parts being riveted together, substantially as andfor the purpose specified.

4. The combination with a well-bucket bottom provided with a centralorifice, of a yoke adapted for movement within the orifice, and carryingatits lower portion a stop of greater length than the diameter of theorifice, and at its upper portion a concavo-convex exteriorly-reinforcedpacking the stop operating as a counterweight to eifect positive seatingof the valve.

5. A valve for well-buckets, comprising'a yoke havingits upper terminalsbent to form inturned arms, a transversely-disposed stop secured at thebend of the yoke, a concavoconvex flexible packing, a concavo-convex capof less diameter than and disposed upon the packing and rivets passingthrough the cap and secured to the said arms.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two Witnesses.
